甘藷粗澱粉率之遺傳及其與塊根收量等性狀相關之研究

Abstract

利用甘藷逢機交配集團第5世代中，逢機選取32個植株為親本，及由每親本逢機交配所得後商之兩個地點的親子兩代試驗資料，探討甘藷塊根粗澱粉率及塊根乾物率之遺傳及其與塊根收量等性狀關之關係，以供為選育高澱粉品種之應用。 Thirty-two plants selected at random from the fifth generation of randomly intermating sweet potato population and their respective open-pollinated progeny grown in two environments were used to estimate the inheritance of crude starch percentage and percent dry matter of roots and correlations between percent crude starch and fresh root yield in sweet potato.
